SUBSTITUTE MATERlAL FOR GAUZE.

SPECIFICATION forming part of Letters Patent No. 727,146, dated May 5,1903.

Application filed January 29,1903. Serial No. 140,992- (No specimens.)

To aZZ whom it mag concern:

Be it known that I, ROBERT W. J OHNSON, a citizenof the United States,residing at New Brunswick, in the county of Middlesex and State of NewJersey, have invented certain new and useful Improvements in SubstituteMaterial for Gauze, of which the following is a specification.

The object of my present invention is to provide a neat, efi'icient, andinexpensive material which shall be adapted to all the needs andpurposes for which gauze is now used by dentists, physicians, surgeons,and others.

Stated in general terms, my invention em bodies a material or structureconsisting of a Referring to said drawings, 01. represents a thin sheet,Web, or ply of cotton, and b b are coincident plies or sheets of verythin tissuepaper, which act to sustain and carry the cotton betweenthem. The material may consist of one ply of absorbent cotton faced onboth sides with paper, as shown in Figs. 1 and 2, or, as shown in Fig.3, it may consist of several separate plies of cotton and theprerequisite number of sheets of paper.

In carrying out the process of my invention the paper in conjunctionwith the cotton, arranged as above explained, is mois tened and thenpressed by running it through a pair of rollers. In some instances aslight amount of starch or other sizing material may lole material.

be added in very minute proportions for the purpose of making the sheetsadhere together; but generally if dampened properly and dried carefullythe moisture, together with the cotton, causes the-component parts ofthe fabric to adhere sufficiently to produce a soft flexi- The finalresult is a cheaper, better, and far more absorptive material thangauze, and the paper facings cover the cotton fibers, so that they donot get into the wound when used as a wound-dressing.

The material may be out into the form of napkins or handkerchiefs fordentists, and in order to give the napkins a nice appearance thepressingrolls may be embossed. The material is, however, valuable inother instancesfor example, wound-dressing in surgery and for otherkindred purposes.

It will be obvious to those skilled in the art to which the inventionappertains that modifications may be made in details without departingfrom the spirit and scope of the invention. Hence I do not limit myselfto the precise mode of procedure hereinabove pointed out; but,

Having described the nature and objects of the invention, whatI claim asnew, and desire to secure by Letters Patent, is

1. The process of making a substitute material for gauze, which consistsin forming a compound fabric of alternate thin sheets of paper andcotton, applyinga sizing material, and subjecting the fabric to exertedpressure.

2. A substitute material for gauze, consisting of a compound fabric ofalternate thin sheets of sized tissue-paper and cotton, substantially asdescribed.

In testimony whereof I afiix my signature in presence of two witnesses.
